Scatter plot of Caregiver (Proxy) Report versus Patient Self-Report for Patient Symptoms on 4 Scales: a SymTrak multimorbidity scale; b PEG pain scale; c PHQ-8 depression scale; d GAD-7 anxiety scale. Higher scores on all 4 scales indicates greater (worse) symptom severity. The solid straight line represents theoretical perfect agreement and the dotted lines are the measurement error bars representing ± 2 SEM (standard error of measurement). The solid curvilinear line represents the fitted actual agreement derived from linear regression and the shaded area represents the confidence limits around the actual agreement
